We have been using this path to detect whether Full Disk Access is granted: ~/Library/Application Support/com.apple.TCC/TCC.db Since macOS [27], reading this path fails with access denied even when Full Disk Access has been granted to the app, so the check now reports a false negative. Questions: Is there an API an app can use to detect whether Full Disk Access has been granted to it? 2. If not, is there another supported method to detect it? 3. If this path is no longer usable, which path can we probe to reliably determine that Full Disk Access is granted?
